[0024] The height of the sewage filtering dam 32 is higher than the water level of the pond 1, and the hollow brick dam wall 43 is made of honeycomb bricks.

[0025] Working method and principle: The water pusher 6 pushes the water toward the drainage end of the breeding tank 2, and the water in the sedimentation and fishing pool 9 is pumped into the residue filtering device 15 for filtration. The filtered water then flows into the sewage purification area 4 for layered purification and then flows back to the breeding tank 2 to realize circulation, so that the water in the pond 1 flows. The trumpet-shaped water inlet is located at one end of the breeding tank 2 with a large opening. After entering from the trumpet-shaped water inlet, the water flows out in a divergent shape, which can fully push the feed and excrement located at the front end of the breeding tank 2 to the rear end. A part of the bait baffle 8 is located below the water surface of the breeding tank 2. The bait uses foamed feed, which will float on the water surface after being put into the bait baffle 8 to block the feed and reduce the feed from entering the sedimentation and fishing The filter plates 5 at the water inlet end and the filter plates 7 at the water outlet end prevent the fish from escaping, and the fish's excrement passes through the filter plates 7 at the water outlet end into the sedimentation fishing pool 9 along with the flowing water. Since one end of the sedimentation fishing pool 9 is closed, a vortex will be formed in the sedimentation fishing pool 9 after the water flow is blocked, which is convenient for the sedimentation of residues. When fishing is needed, the fishing net box 10 is first placed at the bottom of the sedimentation fishing pool 9, the filter plates 7 at the water outlet end are opened, and after the fish are driven into the sedimentation fishing pool 9, the filter plates 7 at the water outlet end are closed, and the gantry crane 11 lifts the fishing net box 10 for fishing. The shape and size of the fishing net box 10 match the sedimentation fishing pool 9, and the above actions can be repeated repeatedly to quickly catch the fish in the breeding tank 2.

[0026] The sewage enters the filter cartridge 17 from the feed guide pipe 50. After the sewage falls on the spherical cover 24, it will splash onto the wall of the filter cartridge 17, so that the sewage can fully contact the wall of the filter cartridge 17. The filter cartridge drive motor 18 drives the filter cartridge 17 to rotate, and the sewage is separated into solid and liquid by centrifugal force. The liquid is discharged into the shell 16 through the filter holes in the wall and discharged from the discharge port of the shell 16 to the first wetland purification pool 30. The solid is deposited at the bottom of the conical surface of the filter cartridge 17. The arc scraper 22 and the slag discharge pipe 20 are fixed. In this case, the filter cartridge 17 rotates counterclockwise. When the filter cartridge 17 rotates, the arc scraper 22 scrapes the solid sediment into the slag discharge pipe 20, and the solid is discharged and collected from the slag discharge pipe 20.

[0027] Sewage purification method, aquatic plants are planted on the first wetland purification pool 30 and the second wetland purification pool 34, the top soil of the first wetland purification pool 30 and the second wetland purification pool 34 is located below the water surface, and the top of the sewage filter dam 32 is higher than the water surface. The sewage is sequentially purified by the first wetland purification pool 30, precipitated in the sewage sedimentation pool 31, filtered and purified twice in the sewage filter dam 32, aerated and oxygenated in the aeration pool 33, purified three times in the sewage filter dam 32, and then enters the biological purification pool 35 for four purifications. Bottom-sinking plants are planted in the biological purification pool 35 When breeding filter-feeding fish, sewage enters the breeding tank 2 after multi-stage purification; the front end dam wall of the sewage filter dam 32 is the water inlet end in the water flow direction, and the rear end dam wall is the drainage end. The upper layer of the front end dam wall is a solid brick dam wall 42, and the solid brick dam wall 42 has poor water permeability. The lower layer of the front end dam wall is a hollow brick dam wall 43, and the hollow brick dam wall 43 has strong water permeability. Sewage enters the dam body from the lower layer of the front end dam wall, and is filtered through the gravel layer 41, the shale ceramsite layer 40 and the base soil layer 39 in turn, and then seeps out from the upper layer of the rear end dam wall for filtration. Vegetation can be planted on the base soil layer 39 of the dam body.

[0028] The function of the retaining wall 45 is to prevent the sludge in the biological purification tank 35 from entering the breeding tank 2 during the flow of water.

[0029] The oxygenation device 46 can add oxygen to the breeding tank 2, and the bridge plate 47 is convenient for the staff to catch and feed.

[0030] The hollow brick dam wall 43 is a honeycomb brick, and the pore size of the honeycomb brick is 5-10 mm.
